Specicaton of Letters Patent.

T o all 'whom t may concern:

Be it known that I, l/VILLIAM VVoLFn, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in Paste-Applying Devices, of which the following is a specification.

This invention relates to a device for applying paste vto the lifts used in building heels, and has for its object to provide means for automatically and rapidly applying paste simultaneously to both sides of the lift, the lift at the conclusion of the operation being in position to be picked up by the operator and placed in position on a similar lift against a heel gage. Heretofore this operation, so far as I am aware, has always involved handling thelift by the operator, either in dipping the lift into the paste or holding the lift in contact with a roller revolving in a paste receptacle. Either of these methods involves considerable waste of the paste, owing to the fact that more paste is taken up by the liftthan is necessary, and a great amount of the paste adheres to the fingers of the operator, making the operation in addition exceedingly uncleanly.

According to the present invention, the operator places the lift on a moving carrier which delivers it between two rollers revolving in close proximity, the under roller be ing partly submerged in paste. The lift passes rapidly between the rollers and is delivered onto a support where it may be picked up by the operator and placed in position. This process insures the paste being applied uniformly to every part of the lift, and on both sides thereof, whereas in all former operations involving the holding of the lift in the hands ofthe operator while the paste was being applied thereto, that portion held between the fingers of the operator frequently has no paste applied to it.

A further advantage yof my invention re sides in the fact that as both sides of the lift have the paste applied to them, it is only necessary to pass every other lift through the pasting device.

The present invention, as a whole, is described and illustrated in connection with a heel building machine in my application for patent on such a machine, filed January 3rd, 1911, Ser. No. 600,611.

In the accompanying drawing: Figure 1 is a plan View of my improved paste applier; Fig. 2 is a transverse sectional view thereof; and Fig. 8 is a sectional detail on the line 3 8 of Fig. 1.

Referring to the drawing, 8 indicates a receptaclefor containing paste. This receptacle 1s mounted preferably on the right hand side of the machine, indicated by the broken portion Il of the drawing, and as more clearly shown by the drawing of the application above mentioned, and is within easy reach of the operator. Mounted in suitable bearings in the sides of the receptacle 3 is a shaft 5, on which is ixedly secured a relatively large roller 6, which is adapted to rotate within the receptacle 3 in a direction toward the machine, and having its bottom located reasonably close to the bottom of the receptacle 8, which is shaped to have a portion of its bottom concentric with the periphery of the said roller. The roller 6 is preferably constructed of wood, but any other suitable material may be employed.

7 indicates a roller preferably of brass, or other metal, which is of the same width as the roller 6, and is located above and out of contact therewith, but near enough to the surface of the roller 6 to take up paste therefrom. This distance, in practice, is about an eighth of an inch.

The shaft 8 of the roller 7 is mounted at opposite ends in bearings 9 at the upper ends of guide-rods 10, located, respectively, on opposite sides of the receptacle 3, said rods being slidably mounted in suitable housings 11. Mounted on one end of the shaft 5 is a relatively large gear 12, which is in mesh with a spur-gear 13 secured on a corresponding end of the shaft 8. An angle arm 14: is mounted on the top of the receptacle at the inner side thereof, and is provided with a series of horizontal extensions or fingers 15, the outer ends of which are beveled and rest upon, or in close proximity to, the surface of the roller 6. These arms are located at suitable distances apart throughout the length of said roller, and form a take-off device in the nature of a grid for the reception of the heel lift after it has passed between the rollers 6 and 7. The sides of the receptacle 3 are extended and shaped to provide bearings 16 in which is rotatably mounted a shaft 17, having on its inner end a pulley 18.

The numeral 19 indicates a rectangular frame, which at its outer end is provided on opposite sides with two bearings 20, through which bearings the shaft 17 passes, whereby the frame 19, as a whole, is pivotally mounted on said shaft. The frame 19 is provided on opposite sides at its inner end with two cylindrical casings 21.

The numerals 22 indicate two arms, each of which has a cylindrical extension 23 entering and slidably mounted in the casing 21. Mounted in the rear end of each casing 21 isa screw 24 which abuts against the outer end of the extension 23. At the end of each arm 22 is provided a bearing 25, in which bearings are mounted the opposite ends of a shaft 26, carrying a roller 27. Mounted on the shaft 17 is a roller 28 considerably larger than the roller 27, and over these two rollers is passed an endless apron 29, the said rollers and apron being of the same width, or substantially so, as the roller 6, Aand thevsmaller roller 27 being located relatively close to the upper part of the said roller 6. The shaft 5 has mounted thereon a pulley 30, over which pulley and the pulley 18 is passed a belt 31. A driving shaft 32 is provided with a pulley 33, whereby it may be driven from a suitable source of power, the shaft 32 being supported in a bearing 3i and being suitably connected to the shaft 5, as indicated at 35.

The numeral 36 indica-tes a doffer-block which is adj ustably mounted in slots 37 provided in opposite sides of the receptacle 3, the inner end of said doffer-bloclr being maintained in more or less close relation with the roller 6 to regulate the amount of paste which shall be carried up by said roller to the roller 7, or the under side -of the lift passing between the rollers 6 and 7.

The numeral 3S indicates a guard for the roller 7, which is preferably provided with an outwardly-extending, upturned edge portion 39 on its inner side, to provide a free clearance space for the lifts delivered between the rollers by the carrier 29. The roller 6 is driven directly from the shaft 32, and as it rotates it carries up paste to the roller 7 which is caused to rotate by engage ment of the gears 12 and 13. The belt 31 causes the shaft 17 to revolve whereby the endless apron 29 is caused constantly to move in a direction toward the roller 6.

In use the operator places a heel lift on the apron 29 which rapidly discharges it upon the surface of the roller 6, which, in turn, carries it underneath the roller 7 and discharges it on the grid formed by the bars 15 where it may again be picked up by the operator to be placed in position on the heel gage. Surplus paste deposited on the grid 15 will, of course, in time pass back into the receptacle 3. When it is desired to replenish the supply of paste in the receptacle 3 the frame 19, as a whole, may be turned backward on the shaft 17 as a pivot. By turning up the screws 2-1 to press the arms 22 outward, I thereby maintain the requisite tension on the apron 29.

Various changes in the form and construction of the device, and in the method of driving the same, may be made without departing from the spirit of my invention.
